last week I posted about my lower carb. I could screw the adjustment all the way in with no affect on the engine. this week end I checked the compression and the 1 thru 4 has 135 lbs and 5 and 6 has 130 lbs. I also checked the plugs and have hot fire on all 6. the carbs have been rebuilt including float. I noticed that the little round plug or cap on the side of the carb was missing which shows 2 tiny holes. would this cause the carb to do this and should this plug be air tight. I mentioned that I could not get it to idle below 900 rpm but if I turn the distributor by hand the motor will idle down to about 650 rpm but the spring on the distributor takes it back up after releasing the dist. do you think that I might have it timmed wrong. the motor does not miss and it has a lot of power, I just want to make sure that the carbs and everything alse is set in the correct mannor.<br />any info will be appreciated.<br />thanks

Re: question for clams

Those small holes are the passages for all low speed fuel, replace the soft plug and seal it with sealer 1000, nail polish or a like product, then slow the idle down with the idle speed screw--Bob

Re: question for clams

laddies, the idle stop screw backs out to 900 rpm and then does not touch the distributer anymore. I can turn the dist by hand to lower the rpm but the spring in the dist takes it back up to 900 rpm again.

Re: question for clams

You need to readjust the throttle cable so it can push the arm to the idle stop

Re: question for clams

That cap/plug on the carb *needs* to be replaced and then seald on there. Airtight it must be.<br /><br />Perhaps with it fixed the dist will then be within adjustment range.
