I have a 1978 235hp evinrude i have new power packs and i found one cylinder with no spark using my timing light and another cylinder had a hit and miss spark. I had some extra coil packs laying around so i swapped the coil pack out got good spark but now the cylinder above it went out. put...
I have a 1978 235hp evinrude . I can't for the life of me get the idle to come down. It all started when i changed the plugs. I retarded the timing as far as it would go back performed sync and link did everything. The best i could get the idle to go down to was 1100rpm in neutral motor is in...
I have a 1978 35 evinrude I did a spark test and all 3 cylinders are dead on the right bank Cylinders 2,4,& 6. I was wondering if anybody knows how to test the power pack. I tested the timer base and that is fine. It also appears the volt meter is not going above 13 volts where as before it was...
I have 78 235 evinrude i changed the fouled plugs and now i can't get the idle to go below 2000rpms. I tried the idle screw, link and sync, followed the shop manual nothing is working. I tried adjusting the throttle cable when i get the throttle arm to move back and get the rpms down to around...
I have a 78 235hp evinrude i was idling perfect at 900 in neutral and 650 in gear. I put in new spark plugs and the idle picked up to 1200 in neutral i tried adjusting the idle with the idle screw and the barrel wheel on the throttle cable and i could only get it to drop around a 100rpms...
I was just wondering what could be causing the motor to pop and spit at low rpms only in idle position. When i manually bring the rpms up with the throttle linkage it starts spitting and popping. If the motor is trimmed up out of the water and i crank it it's like a back fire. When i take the...
I was just wondering if anybody could help i have 78 235hp evinrude just put in 2 new thermostats and one head is not cooling. The other 1 and the power head are cool to the touch this one you will burn your hand on. I took the thermostat back out and checked to make sure it was popping and it...
On my 78 235hp evinrude i have 2 thermostats i really don't know if they are in or not. The temp just about goes over 100 degrees while running wide open or idling. When i shut it off and let it sit and then turn the key to the on position it goes to 160. Just wondering if i will do any harm...
On my 78 235hp evinrude i can't seem to get the idle down. There is no idle screws on the carbs timing is set at around 8 at idle. I loosened up the cable adjusted the cold choke setting put the cable back into into the holder and turned the barrel style adjuster and it didn't make a difference...
I have a 78 235hp evinrude at idle the rpm's go up about a 100 and go wright back down. I'm wondering if it is spark related may be a weak coil or fuel related may be carbs.I just rebuilt both fuel pumps because they were spitting fuel but that didn't change anything. I tried squeezing the fuel...
Does anyone know how to test a temp sender.I put on a new one with a new gauge and i get no reading it stays buried below a 100. I checked power to the gauge have 12v i have a good ground and have the sender wire in the wright spot. I tried to ohm out the sender and i got .009 i don't know if...
I have a 78 235hp evinrude that is spitting and missing slightly at low rpm.If i manually hold the throttle open at about 2000rpm it is very noticeable.It runs perfect at high rpm's no missing at all. Everything has been redone on the motor rebuilt carbs, rebuilt fuel pump, checked spark...
I have a 235hp evinrude i did a compression test and the results were as follows. Cylinder 1 - 0 2- 105 3-0 4- 105 5-100 6- 105 i also did a wet test and the results on 1 & 3 did not change. I did see a little water in those cylinders but i was told even with a blown head gasket you would still...
