this is the 5th in a series of nitro to gas conversions.. In this video I show how the engine can be switched from a spark plug to a glow plug and still basically run the same.. some minor fuel adjustments would be needed.. but other than that.. the engine runs the same on spark or glow ignition..
just remember.. some where in my videos I talk about fuel.. what I use here in canada because the low grade can contain up to 15% ethanol.. so one day it might have none and next day 15% .. so I purchase the high grade with no ethanol and then add the ethanol myself to control the amount needed for the glow plug..
Hi Gary thanks for your interest.. but first off ,, nitro carbs are not a good carb for gasoline.. simply being that a nitro carb is designed to allow 3 times the amount of fuel to the engine than what a gasoline engine needs.. not to mention the seals in a nitro carb to not react well to gasoline since they are meant for alcohol .. two completely different fuels.. my carb for smaller engines was the evolution brand which are no longer made.. I tried the NGH ones but they are just pure junk.. the OS carbs would likely work fine ,, I just have not tried one yet.. very expensive and you would need to make an adapter to mount it to a nitro engine.. I have not really looked at the saito versions yet.. but from what I have seen they only seem to use the negative pulse of the engine to pump fuel... not sure how well that works.. but they don't seem to sell a lot of them.. for now it would seem that we are limited to what we can fit a warbro carb to.. check my other videos.. I have an OS 91 four stroke running on a warbro 15cc carb.. works pretty well..
I have an OS 61 FSR ABC which carb would you recommend for it? It currently has a OS 7D carb on it which has a fairly large opening compared to a OS 60 or a K&B 61 which I'm familiar with
Hi Jeff. Great accomplishment. I'm just getting into trying a conversion. I have several .45-.65's and several Saito's 56, 72 and 100. So, if I have this right: 30:1 Fuel/2-Cycle oil; 15% methanol and a Type-F or G5 plug; an evolution or Walbro 15cc carb? Could you confirm this Jeff? Thanks!
Happy to hear you liked the vids.. and yes a good !! quality synthetic oil is recommended.. use a high octane fuel or a fuel that you know contains zero ethanol.. this is the base , we add the methanol or ethanol in a controlled manor.. here in canada the pumps say ! " may contain up to " that is the catch.. you don't know day to day.. so the plan is start with pure fuel then add.. adjust according to engine performance.. little up or down.. the G5 is the best plug to use.. it was designed for gas engines.. stay away from NGH carb's they are pure crap
