Thread: won't idle

Tweet

Ok, I've got it to idle, kind of. I drove it around but seem to be running low on vaccuum (I hit the brakes and it feels like manual brakes, plenty of pressure at the pedal just a little slow in stopping), so it's not the proper idle mixture. Also seemed a little lean. I tried putting a vacuum gauge on the timed side of the carb and on the port side but neither showed any vaccuum reading while the engine was idling (poorly). I sprayed a WD-40-like spray around the carb base but didn't change the engine running. I also sprayed the vacuum ports (the two in front) while it was idling (poorly) and it didn't change anything. Is there a different place to check vacuum while idling? Thanks for all the help!

can you check at the brake booster?

Spraying into the vacuum ports should have made a difference if the spray is flamable (or for the worse if it isn't) Use the big 3/8 vacuum port in the lower/front of the carb. Are you positive you have the correct intake/carb gasket?
