Question for the carb gurus

[GSpreeman]

I'm tring to start the car after it's sat for a few years. So far no luck.

I had a little time yesterday so I cleaned the fuel pump filter...it really
didn't look at all dirty. When I look down the carbs and move the throttle I
see a fuel dripping down into the carb for cylinder 4, none of the rest.
I've cleaned the idle jets but still nothing. So, I just unscrewed an idle
jet and moved the throttle expecting to see fuel dripping down somewhere but again, nothing. Does this mean that I need to take apart the carbs and clean them out? Any ideas?

Thanks all,

Greg Spreeman

Type of carbs may be helpful but it sounds like either your squirters are clogged or the accelerator pumps have an issue. Being that 1 squirter is working, it may be the rest are clogged. These give the fuel when transitioning from idle to the main jets. The idle jets may not have had enough vacuum pulled on them to get fuel flowing through the carbs yet or may also be clogged. Long and short of it is it sounds like they need to broken down and cleaned.

I'm in the midst of rebuilding my carbs. It's fairly cheap and easy, but definitely time consuming. It's been a winter project for me since the car's been off the road. The exploded parts diagrams make my brain hurt, so I took short videos of each bolt, screw, needle, etc. as I removed them, then assigned each a letter and labeled a ziplock bag with that letter and added parts cleaner to soak. Reassembly was a snap.

Allen, I'm running Dellortos.

Not a good idea to let a car sit for years without running. Fuel starts turning to varnish after sitting for a few months, and after a year or more, will clog your carburetor and other important fuel system parts.

I would drain all the fuel out of your tank and replace it with fresh fuel, prime the fuel lines (purging them of any old fuel), then disassemble and clean or rebuild the carbs.

For the future, it's a good idea to run it and let it get up to operating temperature at least once a month. Cars deteriorate more from sitting than driving!
