Peter2021 Posted March 24, 2021 Share Posted March 24, 2021 Hi guys my son has had his buggy for about 2 weeks from new from RC modelez his first pull start coil was mashed then ordered another pull start and it's just snapped again😞 he is gutted literally had it out 4hrs from new and the compression on engine feels way to hard to pull over but we thought it was down to not been run in properly but he has run the car in properly now and the compression feels really tight🤦🏻♂️ any thoughts guys I've emailed RC modelez for support requesting for a engine check as that what we think it is we've spent 500+ on the car and pull starts feel gutted for him we've done everything by the book also.

hamradioguy Posted March 24, 2021 Share Posted March 24, 2021 If you losen the spark plug does the engine turn over easily ? There is a knack to starting those engines and its really easy to flood them. 1 Quote Link to comment Share on other sites More sharing options...
Nitroholic Posted March 24, 2021 Share Posted March 24, 2021 I have a KM001 .... bought it a few years ago, and its been very modified since then...but... the pullstart on the stock motor was not a good quality item. I actually sold on the stock motor and replaced it with a better unit. It may be the pullstart is binding, and it's not compresion you are feeling. The old start routine used to be ...prime until primer bulb is full, choke on...3 pulls...choke off...start. 1 Quote Link to comment Share on other sites More sharing options...

Yes it is flooded but the pull start has snapped also so can't do anything Quote Link to comment Share on other sites More sharing options...

And the second pull start was no better, instructions with car also poor, my son has had no luck with petrol RC cars think he picks the **** ones all the time pardon my french but feel for him and RC modelez don't help even though we spent to us a expensive car to others it's cheap. Hopefully get it resolved. Cheers nitro 👍🏻 Quote Link to comment Share on other sites More sharing options...
Nitroholic Posted March 24, 2021 Share Posted March 24, 2021 The pullsyarts for these motors are pretty universal. You can also replace the cord, which isn't hard to do. You can get pyllstart cord on E-Bay for a few £££ 1 Quote Link to comment Share on other sites More sharing options...

Nitroholic Posted March 25, 2021 Share Posted March 25, 2021 The stuff I use is 4mm thick. 3mm is probably fine, but stronger cord is no bad thing. Also...I would advise a check of your pullstart technique. It's not just pulling until it won't go any further when starting. Make sure you pull in line with the point where the cord exits the housing...and if you pull the pullstart until it phjysically stops...don;t 🙂 Always stop pulling before the cord is fully out or you will pull it out of the centre pulley or chafe it through. These motors do not have high compression, and don;t need much effort to turn them over fat enough to start. If they won't start...something is making it unhappy 😉 3 Quote Link to comment Share on other sites More sharing options...
Peter2021 Posted March 26, 2021 Author Share Posted March 26, 2021 (edited) Yeah cheers nitro I've been pulling the start crouched to car and pull to chest,it keeps flooding the engine and we start with choke on until it fires then choke off to start normally and the son normally pumps bulb a few times before, thank you for advice mate for pull cord also really appreciate it dude 👍🏻😁 I'll take advice also thank you 😊👍🏻 Edited March 26, 2021 by Peter2021 Quote Link to comment Share on other sites More sharing options...
