Is anyone familiar with the Robin 35 EHO. Mine quits running when it gets warm. I think all it is, is that the idle needs to be pushed up just a tad. But I'll be darned if I can find an idle adjustment anyplace. Mixture screw I've found, but no idle. I've looked in the manual and it doesn't show one either. So, how would I up the idle a tad. In Phoenix here it gets really really warm. Well, actually HOT and I mean HOT

A friend has an EHO35 so i'll ask him when he gets home from work but till then if noone answeres your question Zev the only thing i can think of is any idling adjustment is done via minor increases/decreaases in throttle cable tension.

That's what I was thinking also Fetor. Thanks. I really hope there is an idle adjustment screw tho. So much easier.

http://www.robinamerica.com/engines/detail.lasso?mdl=EH035# Here is a link to the product page for the EH035 if you look to the right side of the page you will see links to downloadable versions of the various manuals for this engine. On page 14 of the Owners Manual it shows the location of the idle adjusting screw. It may be in the Service Manual as well but I didn't look that far.

Hmmm thanks OCScully. I have the manual and saw that. But if I give it like a 1/4 the engine starts smoking, so I just thought maybe in was the mixture adjustment. Turned it back down and smoking stopped. I dunno.

Hi zev0, on my 035 I have the carb off half the time due to my hydro exp. But, that is the only idle adj that i know of. If I were to turn my idle screw 1/4 turn it would make the engine scream and then run ruff. I have to barely turn it to make it idle up. Is your air filter clean, and you have fresh gas? Oil full, so its not overheating? If the engine has sat for a long time run a teaspoon of seafoam along with a fresh tank of gas.

Yup, yup... North or South... Seafoam is loved by all. I've never seen an auto parts store that didn't push seafoam & lucas oil like crazy. They're both worth it.

Did you ever get that worked out? what was the problem with it? I am super interested because I have one coming and I live here in the heat. Now I am running a Honda gx35 (close to the eho35) on a friction drive with no real problems. It seems like you got a defective unit because my 35cc 4 stroke zips along ok so far.
