It was warm yesterday.. Is your edelbrock still having peculation problems?
Yes I thought about that, yesterday was the warmest day of the year for us at 77, I thought I had the peculation issues whipped when I put the heat insulator gasket on it because at that time it stopped the starting issues. But who knows since it does start with no issues when cold.
Don't mean to pile on here, but is your choke working properly? Easy enough to check cold and hot.
I'll check today.
You could try this. Before cranking, put your foot to the floor so you open the primary butterlfy's all the way.
Hold your foot there and see if it fires the first time you crank it. If it does, you may want to start it like this for a while, put some good gas in it and some additive to clean the ports, change the filter and put some miles on it. If it cleans up, your ok.
If it keeps backfiring, I'd stop driving it and pull the carb off, gets some Berrymans and clean out the port ands valleys, then blow it out with some compressed air.
That would be my approach anyway. Hope you get it licked , good luck Jim!
Thanks I'll give that method a try, concerning if it's only back firing out of one side, at least that's what it sounds like and I noticed a puff of smoke from the drivers side exhaust last time if back fired.
Perhaps you have an exhaust valve that isn't sealing or perhaps is sticking somewhere prior to sealing
The fact that it is happening on the same side all the time would lead me to believe it is a valve issue and not a carb issue or timing issue. However, the starting issue is curious.
I might suggest looking into the carb prior to starting and see if the throttle plates are wet.
Disclaimer...take the stogie out of your mouth prior to putting face above carb.
The engine only has about 1,700 miles on a complete rebuild, of course that doesn't mean it isn't a a valve, had to take it back to the builder for two prior issues as a result of intake and then head gasket leaks weeks after the rebuild. The builder quickly repaired both but my confidence level isn't high.
