*2tc fuel problem on hills*

[Cob604]

hey guys

nyce22- ill double check the piping but im going to need someone to check there to compare it to because its not in my manuals

also does the fuel filter go before or after the mechanical pump

thx heaps

Reading others peoples comments, there is a slight chance it could be a breathing problem, but if it is creating a vacuum in the tank it is unlikely though .. The easiest way would be just to take the fuel cap off & take it for a drive ..

Putting the fuel filter before or after the pump is ok, but especially if its before the pump make sure the fittings are tight as a slight vacuum leak here will certainly effect the pump performance ..

As i have said before you need to check the fuel flow to the carby otherwise you don't really know where you are ..

hey guys

ok not im stumped, i started with a tiny bit over the empty mark on the fuel tank to see it if it was the fuel pickup. so i let it idle at the bottom of the hill again for a few mins, then i took off, in second & throttle about 80% again. it got almost as far as as the last try but died right near the top.
so i drove down & waited a few mins & checked everything again, then i took the FUEL cap off & in second about 80% throttle & it made it to where it use to stall & it died.

im thinking it lasting longer up the hill could be because the fuel filter is acting as a small surge can holding a bit extra fuel that makes it go that bit more.

SO tomorrow im going to replace the timing chain & new leads (can any one suggest any tools i should get for the timing chain eg pulley puller, sst ect or is it just basic tools required)

ill buy a fuel reading gauge tomorrow when i pick up the other parts

***im going to canberra on tuesday with this car so any help will be greatly appreaciated or what to check

thx heaps

How long will you be in Canberra Cob?

If there is an opportunity I can offer another opinion as to what is going on. There are a couple of hills around we can test it on.

I'll PM you contact details if interested.

hey

rodger- im taking the grand pacific drive down, but dont know if its going to make it to canberra so i might have to cut my cruise short which i really dont what to have to do.

ive got today to fix it & im going to take it to a mechanic this arvo if i can fix it

there is a really steep hill have been testing it on, if u can give me suggestions i can go & test & check then be back in about 10 mins to tell you

thx heaps

I cannot offer many more suggestions than written here before. I really need to drive a car for myself to get my take on any problem.

The fuel line from the tank could be partially blocked as suggested above, blow back into the tank with compressed air from the pump end. The line could well be full of mud/rust (from dust/moisture build up) and lacquer from old full lead petrol. Push any gunk back the way it would have come in.

Any kinks or squishes in the hard line from the tank?

All the other posts have validity and it may come down to something that you have not observed. See what the mechanic has to offer also.

hey guys

i just took out the fuel sender on the side of the tank & took some pics of the inside & i think i found the problem
the inside of the tank is full of rust

so im thinking the pickup or a bit is stuck in the line somewhere
all the hard lines & hoses are fine no visibal damage




so anyone got a fuel tank in good condition willing to bring it to me asap for what ever cash they want

hey guys

i pulled out the old tank & blew out all the lines then put a second hand tank in (good condition inside). hooked it all up & now i put about 19 liters in it & it says its just above empty when the old tank said 1/2???

anyway the problem is still there i put 20 liters in it & it got to 1/4 up the hill same spot as always, so i put the clutch in & let it idle for a bit then i took off put it in second & held it at 2000 with about 40% throttle & it went up fine the rest of the way

so im thinking that the ventaliation pipe is blocked (the hose that comes out of the fuel tank & goes around the roof of the boot before following the other lines behind the tank

any ideas or what to try next???

thx heaps

hey guys

on the way back from canberra yesterday it started to kangroo hoop while i was cruising at 100km on the freeway on flat ground, so i pulled over & had a look. the fuel filter was full FOR THE FIRST TIME EVER & the float bowl was a bit under the white dot/ or below specs
so i reved it to 5000 & covered the carby inlet, then before it died, gave it a few pumps & it idle fine
the rest of the way home i stayed in fifth for the hills & used about 20% throttle & it got up all the hills without a problem (even mooney mooney which it always plays up). i thought it was fixed & took it up the hill in my area & it kangroo hopped at the same spot as usual


so im going to check the brass mesh filter in the carby today & adjust the float level again

thx heaps

I would be changing the fuel filter again, especially if you found a lot of gunge in the tank, also the only time i have found those fuel filters full is when they are starting to block up ..

Also if you take of the top off the carby again check the drop of the float, ( ie the swing of the float when its fully down as in a empty carby bowl situation ) there is a tang on the float which you can adjust, because if the float is not getting enough swing, ie the float not dropping down enough it will hinder the amount of fuel coming in .. there is a correct spec, but if you can't find the spec's you could try just adjusting it a little bit to increase the drop, just make sure the needle does not come out to much etc .. Obviously above adjustements are only valid if its runing out of fuel in the bowl & all everything else checks out ok .. Have you yet checked the fuel flow to the carby ???? ..

thx heaps

hey guys

today im goign to pull apart the carby & clean it all out, because last night i got stranded in the middle of no where because the float bowl wasnt getting any fuel.
i pulled off the fuel line & cranked it for 5 seconds & it was easily enough to fill the float bowl + more. so i blew into the inlet on the carby & put it all back together & it worked

its either the brass mesh thing or the needle & seat or float

so ill let u know how it goes today.. but i still dont think its going to fix the hill problem

thx heaps guys
