Wet Plugs and miss

[yourpc48]

OK I still have a miss and occasional pop through the carb in the flathead just taking off, higher RPMs seem ok. Carb rebuilt, wires changed, cap, rotor, points, condensor all changed. Dwell perfect. Timing correct. Compression acceptable. 2 plugs wet foul like their not firing. The number 3 and 4 cylinders. The 1 2 5 and 6 fire just right. Any Ideas???

Post your compression check results.

When I checked them those 2 cylinders were higher than the 5 and 6 cylinders but I dont have the compression tester right now. I didnt keep the paper I wrote the tests on so I will have to do it again. I was thinking that the head gasket might be the problem but got good compression. I did test it cold however and not warmed up. I will try it with the engine at a decent temp and see what I get.

Pull the plug wires with insulated pliers one at a time. Does it effect the way the engine runs a idle? Check the inside of the dist cap for any cacks or tracking. Or if you have the old one put it back on and see if there is any difference.

if the timing is correct, a back fire through the carb could be valves not fully seating.

Try swapping the plugs with a couple of the ones that are firing just in case it is a case of bad plugs...........Tim

I would say that the plug wires could be reversed on 3 & 4 but you say it does run good at higher RPM s . The firing order is 1-5-3-6-2-4 .

The compression in 3 and 4 are at 94 lbs. I have swapped the plugs around and the same holes end up wet. I am going out now to check the firing order. I dont think I have done that but I dont remember. When I put the new plug wires on I put them on one at a time so I didnt get them mixed up. The person before me may have put them on wrong. I go a month or 3 between times I work on the car. Its a real clunker but fun to play with. I will let you all know if the firing order was wrong.

Jerry. You are the winner. I came home to look up the firing order and you had it here waiting for me. Thanks. 3 and 4 were switched. Some dummy switched them and then this dummy (ME) didnt bother to check it. Thank you!

Now you are going to have to buy some rear tires...all that new found power will have to go somewhere............

[yourpc48]

Ran ok on 4 and yes its even better on 6 LOL.

Thank you all for the suggestions. New motivation has been found to finis getting it on the road. It has insurance on it. All the lights and such all work. Need to do a little more brake work and put the rest of the glass in it. I will also have to put tags on it and register it in my name....... I SO WANT TO DRIVE IT EVERY DAY! RIGHT NOW!
