LRP
« on: July 16, 2009, 09:56:26 CET »

Hi Guys,did anyone hear that they are adding some chemical to the lrp fuel?A mechanic told me that they are adding some kind of chemical that is making the petrol very sticky.I had to change the spark plugs twice yesterday and the carburators got blocked.This guy told me that they are not giving anymore lrp to boats and other machines due to this chemical.....Is it possible to start giving unleaded fuel to the boat(outboard 2 stroke johnson)?Or i have to change something?I heard about 2 other guys that were giving lrp and they had the same problem.Tks

I just spoke to my mechanic and told me that 4 more guys called him about this problem,all with the same problem of no accelaration and when you are driving it's like you have a turbo and wants to accelarate but cannot.

Better ask a good mechanic about Lrp and unleaded. I had a Johnson 90 (year of manufacture 2000) and I use to give unleaded. Another thing to consider is to add a carb cleaner to the fuel to clear the carburators. I once had bought a good one from Falzon service station

you may also consult the manual and see if it takes unleaded.

In the past I had a 9.9 with LRP and then I've changed to unleaded but I had to change the 2 stroke oil with another quicksilver one not to make any damages.

camkev check the manual.  I think it will take unleaded.  However since the engine is a two stroke i do not see any reason for any damage to occur. (2s has no valves) for which the " leaded" was used to cushioin the valve seats. But than they where hardened so unleaded ( with  less amt of lead) started being used. The main thing is the octane rating.(non existance here) so i guess that both LRP and unleaded are in the same level. (maybe some ignition timing maybe needed but i dont think so)

I used the carb cleaner when I had a problem - when I accelerated, it wasn't responding like something is stuck... and it did cure it!

camkev RLR has johnson 2+4 fuel conditioner to be added with the petrol. 500ml about Euro 9. You can use it after cleaning the carbs. Personally i think its good . apart from normal running(did not  always add during summer) I also used it every winterising i.e leaving the carbs filled with petrol   (engine  not started during winter) and never had any  float needle  sticking etc . I also  used it for the tohatsu aux and now for the  etec. one use ex 10ml for every 5L

Wath type of carb cleaner do you use for 2 stroke because i didn't find a product which is specified for 2 stroke engines.
