Hi Guys, I have just received my Ellison throttle  body back from the USA after a factory overhaul. In the manual provided I  note that Mogas/premium motor fuel is not recommended for use. I had run my  engine on mogas until my accident and was unaware of any restriction on the use  of particular fuels through these throttle bodies. Can anyone with the Ellison  system comment on how critical this policy on burning only avgas  is and if using mogas is a real no-no. I dont have a problem using avgas  but sourcing it in our area is very difficult and I would like to avoid  using 44 gallon storage drums if at all possible.

  

 Regards

Graeme

Hi Graeme,



What did the overhaul cost?  I might do it too.  I

used local fuel for 2 years until I found it had

unlabeled addatives.

		  From what I was told, they can see the damage from

alcohol right off.  Don't know if it is the seals or
	


if the aluminum body corrodes from it.  Maybe both?  I

haven't called them yet on it.

Hi Kurt, I appreciate the reply. I have heard of people using mogas with the 

TBI but wasn't sure about any issues with its use. I really would like to 

continue using it but not at the expense of any damage it might cause. I 

suspected the TBI had some water ingress and although many suggested I do 

the overhaul myself I decided to bite the bullet and get it checked out by 

the manufacturer. I have listed the work that was required to be undertaken 

by them and the costs. It proved to be a wise move as apparently there was 

some corrosion and damaged parts.



Labor - $151.20 (3.36 Hours (at) $45/Hr.)

    Parts - $108.23

    Shipping & Handling - $54.20



1.  The unit was completely disassemble, inspected and cleaned.

2.  Corrosion area by ICV ground out.

3.  All aluminum parts etched and alodined.

4.  Teflon Insert and Slide Seals epoxied into place.

5.  Body & Regulator built up.

6.  New ICV installed and leak checked.

7.  Cracking Pressure checked and set.

8.  Final assembly

9.  Check and set Idle Leak Rate.



Regards

Graeme

Thanks Graeme,



That helps to know.



I want to continue using car (boat gas on floats) if I

can too.  I wish they would bite the bullet and

convert the TBI's to handle additives without damage

for all of us.
