Hard to Start

rking352

I have an older gas ezgo with the robins 290C 4 stroke engine. It takes forever to get it cranked, but once it is going, it runs like a top. As I try to start, gas will spit from the front of the carburetor and if I give any gas past the lock position of the brake, it floods. Any help in this is appreciated. Thanks in advance.

mine was linkage, barely touch the gas and it was half throttle floor it and carb wasnt opening all the way. i took all the linkage off and adjusted every part made it start easy and made it alot faster. i drove it around with no seat watching what happened

You might also check the valves for gap. But I do agree with #88 up there. Also have you cleaned carb really well?

Thanks, I have cleaned the carbs, but have not thought about the linkage. Pretty good with engines, just new to this type. Tried starting it since this post and through a backfire out the front of the carb, had a small fire. I will back off the linkage and check there. Pretty sure due to the age the valves will need adjusted. Also going to look into the backflow that can be created by a clogged muffler. All suggestions are appreciated. Thanks! Will keep posted.

the air coming out the front does sound like valves. your intake valve is open on the compression stroke. i had the same thing with the clogged muffler. but the motor was using the muffler like an air tank and it would get full of air and blow back out the carb

Pulled the muffler and it seemed good. Pretty sure I am down to the valves. It makes the most sense at this point. Plan to set and gap them this week if a friend who is better at this than I can help. Thanks for the input.

Their not bad takes just a few minutes. The way I learned was from the guys here. Some one but not sure who told me to get to top dead center and then just loosen the lock nut and turn the adjusting screw till it just kisses the valve. then back it of just under a quarter turn. tight the nut back and it should be dang close.
