Pull Start Would not Engage
I replaced the plastic pull start ring with Hanson’s metal one and it engages very poorly. Two out of three pulls the ring stays on the bottom and the rope just pulls without spinning the engine. Plastic and metal rings look almost the same and I don’t think metal one has any casting defects. There are two things I can think of that I could’ve screwed up:

1.I put lots of silicone grease in the pull start assembly. should I clean it out?

2.When installing the ring the clocking position of the ring and the retaining steel plate with “wings” could be messed up. Can someone please post a picture of the pull start removed showing the position of the ring and retaining plate when the rope if fully retracted?

All the help would be much appreciated

hi
i am going to guess it is the grease that is giving you problems , the clocking is not important as the engine can come to rest in any position , the starter dog spins as it travels out to meet the dog on the crankshaft , so position is not important , dana

Thanks Dana
I'll clean it after work this evening and then go fly it for couple of tanks before it gets dark . Hope this will work.

It worked after removing excess grease!
Conclusion:
Too much grease = pull start not engaging or engaging after most of the length of the rope is pulled out

hi
glad to hear that worked for you , i just fit a pullstart to a zenoah 20 EI and it turned out to have a different spacing between the back plate and the crank than a G231 or a G26 , so i was just there scratching my head about the same thing a week ago , turned out with the 20 EI i had to make a longer reach dogplate , dana
